Multi-Active Delivery Essence is a hydrating essence that instantly nourishes and restores skin condition, giving softer-feeling skin. The lightweight skincare essence strengthens the skin barrier after one application and keeps skin hydrated and luminous all day. Multi-Active Delivery Essence contains a specific combination of four active technologies, which effectively boost skin hydration to increase penetration of skincare ingredients. When tested with Niacinamide 10% + Zinc 1%, Multi-Active Delivery Essence was able to increase the penetration of niacinamide by 2 times after 1 hour vs when Niacinamide 10% + Zinc 1% is applied alone1.
